6.5 Acquiring Spectral Doppler Images
Spectral Doppler imaging is intended to provide measurement data concerning the velocity, the direction, and the
category of the arterial or vein ow. It contributes a more accurate qualitative analysis than the color ow imaging.
Spectral Doppler includes Pulsed Wave Doppler (PW) mode and Continuous Wave Doppler (CW) mode.
6.5.1 PW Mode
Pulsed Wave Doppler (PW) is a Doppler mode that measures velocity in a PW sample volume and displays
that information in a spectral trace with audio output. PW includes conventional PW and High Pulse Repetition
Frequency (HPRF). PW Doppler can be combined with the B mode for rapidly selecting the anatomical site for PW
Doppler examination. The site where PW Doppler data is derived appears graphically on the B-Mode image.
